BP2870D

Sample application
Sketch
BP2870D is a constant current driver chip specifically designed for low PF floating ground Buck LED. It adopts full-cycle closed-loop sampling, which improves the constant current accuracy over a wide output range. BP2870D can achieve the function of current adjustment by DIP switch through an independent CS current signal sampling pin.
Advantage

    Full-cycle sampling of inductor current, high constant current accuracy
    Excellent load regulation rate
    Supports ultra-wide output voltage load
    External NTC over-temperature current reduction
    High-precision current reference (+/-3%)

Application area
  • LED three-proof lamp
  • LED strip light
